A friend in need is a Caillou episode.
Caillou and Leo are playing aliens and Leo accidentally trips over a tree and hurts his foot a lot. So, Caillou's Daddy takes Leo to the hospital to have his foot checked. Caillou hasn't been to the hospital before. He is curious on what might happen there. But when Daddy calls about Leo, he says that Leo is already out of the hospital and doing fine, but unfortunately, Leo has a broken foot so he has to stay off his feet for a while. Caillou decides to make a card and some cookies for Leo. Then he heads on over to Leo's house. He gives Leo his treats and Leo tells Caillou that he broke his foot because he forgot to tie his shoelaces. Caillou then plays aliens with Leo.
